" Good eye. I wanted to use the Hossack front end of the 06 and up k12. Those have a swingarm that pivots in the frame, but the transmission is part of the engine block. As I was contemplating this I realized the earlier k bikes used a separate trans. But you are right - that requires flipping the 04 trans over to meet the left side shaft. If this prove problematic, my next theory is to try and mate a r1100gs trans into the frame. Those had the swingarm pivoting in the transmission casing itself. This would keep the trans in the appropriate orientation, and maybe allow for more spacing with my (obscenely long) motor, but I would have to move the shock mount to the other side of the frame along with figuring out how to mount the trans in the frame.

Choosing the solution becomes something of a chicken and egg problem. I'm trying to figure out which way to go before I try and solve the engine mounts. "

This should give me choices from 5.78:1 to 2.31:1.
Curious why you'd go with two different gen BMWs for swingarm and transmission. That trans is made for a right-side swingarm, while the '06 is a left side. (I rode an '02 K1200RS up until I traded it in a month ago.) For that generation transmission, the flywheel/clutch slides over splines on the engine output shaft, and is bolted in place with one bolt right down the center. There's a complete parts fiche online at realoem.com if you haven't found it yet.

I'm watching with interest! "

Here is the drivetrain mocked up into the frame w/ suspension. Not having final spacing on the connection between the motor and transmission shafts makes me nervous about front wheel clearance. "

" Ideas? The Lovejoy L110 jaw connectors I got are huge. I hadn't counted on the extra spacing. The L95 I picked up to check sizing are the right size but are underrated for the torque. They make a size in between, but that means they will be slightly too big AND slightly underrated.

" The transmission is mostly to connect the motor to the shaft drive, while achieving both offset (centering the motor) and the appropriate reduction. The ability to change ratios is a bonus.

I'm not familiar with the Impact 9 - do you mean the Impulse?

Yes, a smaller motor would probably be more efficient. But it wouldn't be as interesting. "

" You'd be better off with a smaller motor and bigger controller (ex. Z1k). It really depends on your goals. Also, while the tranny idea is neat, unless you're racing it's not really necessary. Then again it's not that big, lol. Have a look at the ImPact 9 also. "

The dual motors are very cool but I can only run a single if I want to use the stock swing arm. Plus I need the spoked version to keep the bike looking period-correct. Although the seller is actually local and he is selling the motors for a great price so it is really upsetting to have to pass up on them. If I had some sort of a modern-looking street bike, I would definitely buy them.

Nice project. Is it an Enertrac 602? What voltage do you plan to run? I will most likely also be going with Leaf modules. Whenever you get a chance to ride it, please share your top speed. "
